What affects the price
HVAC repair costs change based on a few key factors. The specific mechanical issue, the accessibility of the unit, and the age or model of your system all play a role. If a technician needs to source rare or hard-to-find parts, that can shift the total. Additionally, the labor hours required to troubleshoot complex electrical or refrigerant leaks will impact the final bill. Please reach out to speak with a local pro, as exact pricing is confirmed free on the call.

Frequently asked in Ontario
This helps homeowners evaluate the long-term value of repairing an older system versus investing in a new, more energy-efficient one. We can help you assess your situation.
Why is my AC running but not cooling?
This is a common issue in Ontario's climate and can be caused by several factors, including low refrigerant, a dirty air filter, or a problem with the compressor. The unit may appear to be running because the fan is on, but it's not actually cooling the air. A professional diagnosis is needed to identify the specific cause.
What does a typical AC repair cost?
What is the 3 minute rule for AC?
The 3-minute rule for AC systems recommends waiting at least three minutes after the unit has shut off before restarting it. This pause is important to protect the compressor, a critical component of your AC. Following this rule helps prevent strain on the compressor, which is especially beneficial in Ontario where AC units are used frequently.
This is particularly relevant for older HVAC units in Ontario that may be nearing the end of their operational life and could face more frequent, costly issues. We can help you weigh your options.
